Abstract

Procédé pour la fabrication d'un pansement médical polyvalent offrant une protection suffisante contre les bactéries et présentant de bonnes propriétés mécaniques et lyophiles. Une feuille de mousse de polyuréthane à alvéoles ouverts non comprimée de 0,5 à 10 mm d'épaisseur est ramollie à l'une de ses surfaces, sans décomposition thermique, jusqu'à obtention du pouvoir adhésif voulu et est reliée ensuite, de manière perméable aux gaz et à la vapeur d'eau, à une feuille de mousse de polyuréthane souple comprimée irréversiblement de façon que son épaisseur soit réduite de 2 à 30 fois, l'ensemble ainsi obtenu étant ensuite nettoyé par voie physique et/ou chimique. L'invention est applicable en particulier au traitement de brûlures et analogues.Process for the manufacture of a multipurpose medical dressing providing sufficient protection against bacteria and exhibiting good mechanical and lyophilic properties. A sheet of uncompressed open cell polyurethane foam 0.5 to 10 mm thick is softened at one of its surfaces, without thermal decomposition, until the desired adhesive power is obtained and is then bonded in such a manner. permeable to gas and to water vapor, to a sheet of flexible polyurethane foam irreversibly compressed so that its thickness is reduced from 2 to 30 times, the assembly thus obtained being then cleaned by physical and / or chemical means. The invention is particularly applicable to the treatment of burns and the like.
